As Antoine Griezmann considers his future, the FC crew discuss the pros and cons of staying at Atletico and moving to Barcelona.
Having previously stated that he would announce his decision before France's opening World Cup game on Saturday, Griezmann chose to keep quiet.

Aged seven, and wearing the No 7 on his back, he is seen with a friend excitedly running around getting autographs from the World Cup-winning squad.
"I am very sorry, but I will not be revealing my decision today", he said.
Griezmann is looking to cap another spectacular club season, in which he scored 29 goals in 49 games as Atletico finished runners-up in La Liga behind Barcelona and lifted the UEFA Europa League. "I know many people were waiting for that but this isn't the right day to do so". "The decision has been taken but it is not the time or the place to talk about it", he said.
If the Catalan club signed him now, it would cost them €200 million but if they wait until the turn of the month, it will be halved to €100 million.
